Yes, Levi, the next gen 7 will likely contain CFRP, but according to the press it will be the roof, hood, and deck lid just as I suggested the new M3 may use. The i3 will be much lower production numbers which is doable with this material just like the MP4-12C, and Lamborghini and the previous F1 and CarreraGT were. If you look closely at the i3 press photos of the chassis notice the crash structures and lower frame rails are aluminum.
Your right in predicting future mass produced cars will begin using CRFP for stress bearing components, I just don't think it will happen until 2020 or later. Just my opinion, not meant to be argumentative.
